This question is being asked frequently since the start of the Coronavirus pandemic outbreak, which has changed world order significantly. As often, the answer to this question is mixed and depends both on internal (your health issues) and external factors (geopolitical situation in your country).
Since there are no two similar cases we encourage you to ask questions in the comments section and we will address your situation directly.
So let’s go through some typical cases cases:
All of the dental offices in your country are closed
This is not a hypothetical situation that might happen in the future – already there are countries that fully shut down the whole dental services sector. If you are living in such a place the only possibility left may be emergency dental care. We strongly discourage you from visiting such places for treatment that can be postponed and is not urgent. Cases that are serious enough to visit emergency care include pain, bleeding, fever, having abscesses and other serious conditions. Please note that emergency dental care is focused on solving your current urgent problem rather than providing you state of the art restorative services.
Some dental offices operate without change, but your dentist’s office is closed
This situation is slightly better than having only emergency care available but also in this case we recommend only serious cases visits. You may also have a filling if you’re concerned that it will be a deep one or you start feeling pain.
Your dentist office is open and you have upcoming appointment
You should cancel (postpone by a month or more) all the appointments that consist of elective procedures, including regular checkup appointments, dental cleanings, teeth whitening, fillings (except when you’re in pain already), orthodontic and periodontal procedures, implants, and cosmetic dentistry including crowns and veneers.
